“…One can see that α is 90 • , and β is 0 • at frequency ranges of 9.4 to 13.1 GHz and 13.4 to 17.2 GHz, implying that the designed CPC can achieve a near-perfectly linear cross-polarization conversion. In addition, PCR is generally used to describe the polarization conversion efficiency, which can be calculated by [15…”

“…A variety of polarization converters based on different MSs for microwave and optical bands have been proposed. They can be classified as reflection-type [6][7][8][9][10][11] and transmissiontype [12][13][14][15][16][17][18], in which transmission-type converters are easy to assemble as they can be placed at the forward end of the radiation antenna to realize the polarization conversion of the EM wave transmitted or received. Numerous studies on transmission-type converters have been reported.…”

“…The relative bandwidth is 7.2%. Also, a SIW based unit cell with U-shaped slots is proposed in [15], which can convert incident waves into cross-polarized waves at three frequency points with PCR close to 100%. In actual applications characteristics of wide bandwidth, polarization insensitive and larger PCR are desirable simultaneously, which needs more exploration.…”

A linear-to-linear cross-polarization converter (CPC) based on metasurface (MS) is proposed. The converter is polarization insensitive and has two wide bands. The MS is composed of periodical unit cells printed on a substrate. The top and bottom MS unit cells are formed with four groups of right-angle triangle pairs whose vertices are connected. Thus, there are eight pairs of triangles on the top and bottom surfaces of the substrate, and these pairs of triangles are arranged alternately in overlapping and orthogonal ways. The polarization conversion ratio (PCR) of the CPC is higher than 95% in the bands of 9.4 to 13.1 GHz and 13.4 to 17.2 GHz. Additionally, the PCR remains the same when the electromagnetic (EM) wave is incident at arbitrary azimuth. Furthermore, the polarization rotation angle and elliptic angle are calculated to verify the conversion effect. Finally, the conversion mechanism of the proposed converter is explored by analyzing the surface current distribution and magnetic field. The proposed converter can be applied to the field of satellite communication in Ku-band.

“…Fortunately, the emergence of metasurface (MS) brings new hope for the development of polarization converter [4]. Utilizing powerful ability of MS to manipulate EM, people proposed various MSs to achieve polarization conversion, including frequency selective surfaces (FSS) [5][6][7][8][9], tunable polarization converters [10][11][12][13][14], chiral geometry, and anisotropic MS [15][16][17][18][19][20][21][22][23]. Among them, the anisotropic properties of MS are widely used in the design of reflective polarization converters, such as "double-V" [21], "grating" [22], and "split-ring" [23] MSs.…”

In this paper, an ultra-wideband linear cross polarization converter based on metasurface (MS) with wide incidence angle is presented and applied to the reduction of radar cross section (RCS) for planar and conformal surfaces. A pair of bow-and-arrow shaped split ring cells is printed on an FR4 dielectric substrate. The simulated and experimental results indicate that the converter achieves a cross polarization conversion ratio (PCR) of over 90% in 11.5-28.5 GHz (85% relative bandwidth) and that its oblique incidence performance can be stabilized at ±40 • with a very small loss of bandwidth (1.65%). Then, the polarization conversion metasurface (PCM) cells and their mirror cells are laid out in a checkerboard array and applied to reduce the RCS of planar and conformal surfaces. The planar PCM achieves more than 7 dB of RCS reduction in 11.4 to 29.6 GHz (88.8% relative bandwidth), and the conformal array with a center angle of 90 • obtains more than 10 dB RCS reduction in 18.2 to 23.7 GHz. Due to its excellent performances, the proposed metasurface offers promising options for polarization control devices and stealth technology in Ku-and K-bands.
